Concertgoers might have to deal with traffic, parking headaches and outrageous scalped-ticket prices when Metallica opens Chase Center next month.

But at least they won’t have to worry about carnivorous, big cats stalking around and picking off metalheads outside of San Francisco’s shiny, new arena.

A Canadian woman unwittingly proved that cougars — the large feline ones, not the Mrs. Robinson variety — have an aversion to the music of the biggest-selling metal band of all-time.

Dee Gallant and her dog Murphy were recently walking around Vancouver Island, British Columbia, when they spotted a mountain lion sizing them up for lunch. Gallant said she went to her bag of tricks to scare it off, but not until she desperately blasted a Metallica song its way did it cower off and retreat, according to AVClub.

Gallant said she searched for the “noisiest” song on her playlist. She decided on Metallica’s appropriately titled “Don’t Tread on Me.”

“(As) soon as the first notes blared out it ran into the bush,” Gallant said.

Perhaps “Don’t Tread on Me” will be on the setlist when Metallica and the San Francisco Symphony team up to christen Chase Center, the Golden State Warriors’ new home, with a pair of concerts Sept.6 and Sept. 8.
